GEORGE H. BROWN, OF WILKINSBURG, PENNSYLVANIA.

BOTTLE-STOPPER.

Specification of Letters Patent.

llatented Nev. 20, 1917.

Application filed February 10, 191'?. Serial No. 147,844.

To all whom t may concern:

Be it known that I, Geenen H. BROWN, a citizen of the United States, residing at lVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is aV specification.

This invention has relation to bottle stoppers, and has for an object to provide an improved stopper adapted for association with afspeciic form of bottle or other container, and providing means whereby the contents of the bottle or container may be readily discharged when required, and whereby a closure for the container may be automatically formed by the stopper when the stopper' is released.

Another object of the invention is to provide a stopper havingthe above named characteristics whereby the same may be applied ,to a container for either liquid or powder,

and whereby the substance may be dispensed from the container without waste, and without permitting` the entrance of deleteriousv substances into the container.

A still further object is to provide a stopper of this character adapted to be applied to a form of bottle specifically adapted for association therewith, and whereby the stopper may be entirely removed from the bottle when the same is to be cleaned` and whereby the stopper may be again applied after the bottle has been resupplied.

ln addition to the foregoing my invention c'omprehends improvements in the details of construction and'arrangement of parts to be hereinafter more fully described and particularly set forth in the appended claims.

1n the accompanying' drawings in which similar and CorrespOndine,` parts are designated by the same characters of reference throughout the several views in which they appear;

Figure 1, is a view in section of an im.- proved bottle stopper and constructed after the manner of my invention.

Figs. 2 and 3 are horizontal sections taken on the lines 2-2 and 3 3 respectively of the foregoing figure.

4 is a section taken on the line 4, l of Fig. 2, and

Fig. 5, is a sectional perspective illustrating the cap member and a portion of its interior.

With reference to the drawings, l() indilbead 1Q is formed at opposite sides with notches 13, having` their side walls disposed radially. The bead 12 is also provided at points intermediate the notches 13 with smo` .er notches 1l whose walls arc parallel witn the diametrical center of the bottlev neck. Before proceedingv further it is to be understood that l have illustrated as an example the provision of a bottle having a specially formed neck, nevertheless a metal container, or containers having, other configurations may be employed, and similarl)Y provided with a bead having notches, and constructed after the manner herein set forth.

My in iproved stopper comprisesan inverted capmember having a cylindrical wall 16 and a top portion 17, which top portion is perforated centrally as at 1S. The top member V16 is provided interiorly with opposed radially extending lugs 19 of a shape and to correspond to the above mentioned notches 13 of the bottle. A perfo- `rated disk of cork orthe like 20. is inserted within the cap member, and the lugs 1S) should be disposed inspaced relation from the cover portion 17 of the cap member whereby when the cap member is applied to the neck of a bottle, the lugs 19 may be permitted to enter the notches 123 to a degree sul'licient to permit the cap member y to be subsequently rotated whereby7 to dispose the lugs 1S) beneath the solid portion provided between the notches of the bead 12. The cap member is furthermore rotated until reduced portions 21 formed on the upper surface of each lug 19 become coincident with the notches 14e of the bead 12. whereupon said reduced portions 21 may enter said notches thereby lockingthe cap member against accidental rotation.

A valve mechanism forms a part of the stopper and comprises an outer tubular member 22 which is inserted in the opening,` 18 of the cap member and is adapted to extend Well into the neck of the bpttle with its portion slightly projecting beyond the cap. An inner ti'ibular member 23 of a diameter slightly less than that of the outer tubular member, is held concentrically in said outer tubular member and is provided at its inner end with a radial flange 24, which is adapted to bear against the inner end of the outer tubular member. The pposite end of the inner tubular member eX- tends considerably beyond the projecting end of the outer-.tubular member and is eX- ternally threaded as indicated at 25.

\ flange 26 is internally threaded and applied to the threaded portion 25 of the inner tubular member 23, and a coil spring 27 is encircled about that portion of the inner tubular member which projects beyond the cap member and is interposed between the under side of the llange 26 and the outer surface of the cap member being centralizedby the engagement of the projecting end of the outer tubular member. The tubular member 23 is provided with anopening 28 at its inner end, and a flange 29 at its opposite end.

In operation, the bottle or container, .is inverted and the flange 26 pressed against the tension of the coil springA whereby to engage the flange against the outer projecting end of the outer projecting tubular member 22 whereupon the flange 24 of the inner end of the inner tubular member Will become unseated from engagement with the adjacent end of the outer tubular member, whereby 'fiuid is permitted to flow intothe opening 28, through the inner tubular member, and out of the same at its opposite end. .By pressing the flange 26 lightly against the projecting end of. the outer tubular member, suiiicient air may be permitted to enter the bottle to displace the contents which How from the inner tubular member. It will be obvious that when pressure upon the spring is released, the flange 24 will immediately become seated to form a closure for the container to prevent accidental ejectment of its contents. It will also be obvious that when the bottle or container has been emptied, the stopper may be readily detached therefrom, the bottle refilled and the stopper reapplied, Y

While I have illustrated and described my' invention with some degree of particularity I realize that in practice various alterations may be' made, and I therefore reserve the -il wr, I

right and privilege of changing the form ci? the details of construction or otherwise altering the arrangement of the correlated parts without departingfrom the spirit of the invention or the scope of the appended claims.

Having thus described niy' invention, what the notches and lugs out. of alinement, andv reduced lugs formed on the first mentioned notches adapted, when the cap is thus rotated to enter the smaller notches to lock the cap against rotation.

2. A bottle stopper including a cap, a tui bular member open at each end and secured in the cap, a second tubular member open at each end, movable in the first tubular member in spaced relation thereto, a valve on one end of the inner tubular member to close the adjacent end of the outer tubular member, a flange on the other end of the inner tubular member, and a coil spring encircling one end of the outer tubular member to engage the 4flange to retain the valve in closed position, said inner tubular member being movable to unseat the valve against tension of the spring and to seat the flange against the adjacent end of the outer tubular member, to insure passage of material through the inner tubular member and to permit replacement of air in the bottle through the outer tubular member, the flange being slightly unseated for this purpose.

In testimony whereof I aiiix my signature in presence of two witnesses.
